Could also be these thing mentioned, Mission is part of Mathews and most Mathews centershots are right around 13/16 from berger hole to center of arrow on rest. Also is your arrow even with berger hole on rest. Meaning if you looked from side of bow straight on toward your rest you should see the hole where your rest is screwed on to your bow slightly above and below your arrow.
